LP2960IMX-5.0 Equivalent & Substitute Parts

Part Overview

The LP2960IMX-5.0 is a linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) component. It delivers a fixed positive 5V output at 500mA with a maximum input voltage of 30V and dropout voltage of 0.8V at full load. The device integrates over-current, over-temperature, and reverse polarity protection with an enable control feature. Currently marked as obsolete, this part requires identification of active equivalent alternatives to maintain design continuity and ensure long-term supply availability.

Substitute Part Grouping Explanation

Substitution eligibility for the LP2960IMX-5.0 is determined by strict equivalence across the following critical parameters:

Output voltage: 5V fixed
Output current capability: 500mA
Maximum input voltage: 30V
Dropout voltage: 0.8V @ 500mA
Protection features: Over-current, over-temperature, reverse polarity
Control features: Enable function
Package type: 16-SOIC
Operating temperature range: -40°C ~ 125°C

The identified substitute parts maintain identical electrical specifications and mechanical compatibility. Differences in product status, packaging format (tube vs. tape & reel), and RoHS compliance are noted but do not affect functional interchangeability in circuit applications.

Engineering Selection Recommendations

Both LP2960IM-5.0/NOPB and LP2960AIMX-5.0/NOPB are active product alternatives to the obsolete LP2960IMX-5.0. Selection between these substitutes depends on supply chain and compliance requirements:

LP2960IM-5.0/NOPB is supplied in tube packaging and carries ROHS3 compliance certification, suitable for applications requiring RoHS-compliant components with standard packaging.

LP2960AIMX-5.0/NOPB is supplied in tape & reel format with ROHS3 compliance certification, optimized for high-volume automated assembly processes. This variant offers the highest current inventory availability at 4300 pieces.

Both alternatives maintain identical electrical performance and mechanical compatibility with the original LP2960IMX-5.0 design. The choice between tube and tape & reel packaging should align with production volume and assembly methodology.

Frequently Asked Questions (FAQ)

Q: Can LP2960IM-5.0/NOPB and LP2960AIMX-5.0/NOPB be used interchangeably with LP2960IMX-5.0?

A: Yes. Both parts are electrically and mechanically equivalent. They deliver identical 5V output at 500mA with matching dropout voltage, protection features, and operating temperature range. The primary differences are product status (active vs. obsolete), packaging format, and RoHS compliance level.

Q: What is the difference between tube and tape & reel packaging?

A: Tube packaging (LP2960IM-5.0/NOPB) is suitable for lower-volume applications and manual assembly. Tape & reel packaging (LP2960AIMX-5.0/NOPB) is designed for automated pick-and-place assembly in high-volume production environments. Both formats contain identical components.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both ROHS3-compliant alternatives perform identically to the RoHS non-compliant original part in circuit operation.

Q: Are there any pin-to-pin compatibility concerns?

A: No. All three parts use the 16-SOIC package with identical pinout and electrical characteristics. Direct PCB layout compatibility is maintained.

Q: What is the Moisture Sensitivity Level (MSL) difference?

A: The original part has MSL 1 (unlimited shelf life). The substitute parts have MSL 3 (168-hour floor life after moisture exposure). This affects storage and handling procedures but does not impact functional performance once soldered.
